Tshem tawm electromagnetic cuam tshuam (EMI) los ntawm PCB (luam tawm Circuit Board) tsim yuav nyuaj thiab yuav tsum tau ntau theem.Qee qhov tseem ceeb tshaj plaws ntawm cov kauj ruam no yog raws li hauv qab no:
Txheeb xyuas cov peev txheej ntawm EMI:
Thawj kauj ruam hauv kev tshem tawm EMI yog txhawm rau txheeb xyuas qhov muaj peev xwm cuam tshuam.Cov kauj ruam no suav nrog saib cov qauv hauv Circuit Court thiab txheeb xyuas cov ntsiab lus xws li oscillators, hloov cov tswj hwm thiab cov teeb liab digital uas nyiam tsim EMI.
Optimize cov khoom tso rau hauv:
Muab cov khoom tso rau ntawm PCB muab qhov zoo tshaj plaws rau lawv.Tiv thaiv los yog lim cov khoom sib cais pab cais cov hluav taws xob rhiab, lossis koj yuav tsum tau txav cov khoom nyob ib puag ncig kom txo qhov chaw ntawm lawv.
1. Siv cov txheej txheem hauv av kom raug
Grounding yog qhov tseem ceeb los txo EMI.Txhawm rau txo qhov peev xwm rau EMI koj yuav tsum siv cov txheej txheem hauv av kom raug.Cov kauj ruam no suav nrog kev siv lub dav hlau hauv av los faib cov analogue thiab digital signals, lossis txuas ntau yam khoom rau ib lub dav hlau hauv av.
2. Siv cov ntaub thaiv npog thiab lim
Qee zaum, cov khoom siv los tiv thaiv los yog lim dej tuaj yeem pab tshem tawm EMI.filtering Cheebtsam pab tshem tawm tsis xav tau frequencies los ntawm lub teeb liab, thaum shielding yuav pab tau kom tsis txhob EMI mus txog rhiab circuits.
3. Kev kuaj thiab kev kuaj xyuas
Tom qab tus tsim tau optimised, koj yuav tsum xyuas kom meej tias koj tau raug tshem tawm EMI.Qhov kev tshem tawm no yuav xav tau ntsuas PCB cov khoom siv hluav taws xob hluav taws xob nrog EMI tus kws tshuaj ntsuam xyuas, lossis ntsuas PCB hauv qhov xwm txheej tiag tiag kom ntseeg tau tias nws ua haujlwm raws li tau npaj tseg.
Kev kuaj EMI hauv PCB tsim
Koj puas xav tau kuaj EMI hauv koj tus qauv PCB thiab yog tias muaj, cov ntsiab lus hauv qab no yuav pab koj mus txog.Tom qab ntawd, koj yuav xav ua raws li cov kauj ruam tom ntej:
1. Txhais cov qauv xeem
Txhais qhov ntau zaus, kev sim thiab kev txwv.Cov qauv khoom yuav tsum txiav txim siab cov qauv xeem.
2. Cov khoom siv kuaj
Teem lub EMI receiver, teeb liab generator, spectrum analyzer thiab oscilloscope.Cov cuab yeej yuav tsum tau ntsuas thiab txheeb xyuas ua ntej kuaj.
3. Npaj PCB
Rau kev sim, xyuas kom tseeb tias koj nruab tag nrho cov khoom kom raug thiab lub zog ntawm PCB kom raug los ntawm kev txuas mus rau cov khoom siv kuaj.
4. Ua qhov ntsuas hluav taws xob emission
Txhawm rau ua qhov kev ntsuas hluav taws xob hluav taws xob, tso lub PCB rau hauv lub chamber anechoic thiab xa cov teeb liab nrog lub teeb liab lub tshuab hluav taws xob thaum ntsuas qhov hluav taws xob emission theem nrog EMI receiver.
5. Kev kuaj emission
Ua kev ntsuas emission los ntawm kev txhaj cov cim rau hauv lub zog thiab cov kab teeb liab ntawm PCB, thaum ntsuas qhov ua tiav qib emission nrog EMI receiver.
6. Txheeb xyuas cov txiaj ntsig
Tshawb xyuas cov txiaj ntsig kev xeem los txiav txim siab seb tus qauv PCB puas ua tau raws li cov qauv ntsuas.Yog tias cov txiaj ntsig kev xeem tsis ua raws li cov qauv, txheeb xyuas lub hauv paus ntawm cov emissions thiab ua kom raug, xws li ntxiv EMI shielding lossis lim.
